However, these http://www.selleckchem.com/products/Belinostat.html are uncommon at initial presentation and suggest advanced disease.12 Sign and symptoms of maxillary sinus carcinoma could be classified as nasal, ocular, facial, auditory and oral.12 Nasal findings occur approximately 50% of patients and consist of obstruction, discharge, stuffiness, congestion, epistaxis, and extension into the nasal cavity. Ocular findings are seen in up to 25% of patients and arise from upward extension into the orbit, where unilateral tearing, diplopia, fullness of lids, pain, and exophthalmos are seen. Facial signs comprise infraorbital nerve hypestesia, cheek swelling, pain, and facial asymmetry. Audiotory complaints consist of hearing loss secondary to serous otitis media due to nasopharyngeal extension.

Finally, oral presentations arise in 25�C35% of patients and include pain involving the maxillary dentition, trismus, palatal and alveolar ridge fullness, and frank erosion into the oral cavity. Multiple unilaterally missing left maxillary teeth in the presented case indicates to unrealized maxillary sinus fibrosarcoma development, and related pain as a causative factor for previous extractions. It should also be emphasized that although advanced imaging techniques often provide important additional diagnostic information which can help guide patient management, conventional radiographs (e.g. OPG, maxillary occlusal radiograph or periapical radiographs) may also be valuable for the initial diagnosis of a lesion in the maxillary sinus as seen in the presented case.

Since the success in the management and prognosis in cancer patients is highly associated with early diagnosis, suspicion leading to more detailed investigations should be performed when patients do not respond to routine dental therapy. The survival of patients with fibrosarcoma is intermediate (60�C70%) in head and neck region,2 poor (30�C50% for 5-year) in maxillary sinus,13 and worst in gemistocytic astrocytoma (16% for 5-years; 0% for 10-years).7 The overall survival of our patient was 2.5-years. The possible factors influenced the survival negatively were male sex, increasing age, higher TNM staging, site of the tumor (worse in the maxilla) for fibrosarcoma;11 and age, tumor grade and histological type (Grade II poorly differentiated) for gemistocytic astrocytoma.5,7 It was difficult to apply a standard treatment protocol for the presented case due to absence of the similar presentation in the literature.

Therefore, understanding of the clinical behaviors of the tumors in response to therapy was AV-951 also vague. The best treatment protocol for such patients awaits further documentations and investigations. However, in relevance with maxillofacial surgery, wide surgical resection with clear margins is important for a favorable survival, since fibrosarcoma is more of a locally destructive problem (recurrence rate: ~30�C66.7%)14 than a metastatic problem (distant metastases rate: ~20%).
